Question

An $42 item was marked down by 50%

what is the new cost of the item?

Answer 1

New Cost of item is
`\$ 21`

Explanation:

Given:

Original Cost of item =
`\$ 42`

Item was marked down by
`50\%`

To Calculate Cost after
`50\%` marked down we need to multiply original cost by 50 and then divide by hundred.

Cost after marked down =
`(42 * 50)/(100)= \$21`

Now New cost of the item is calculated by Subtracting Cost after
`50\%` marked down by Original Cost of item.

New cost of the item =
`\$ 42 - \$ 21 = \$21`
